I JOSEPH J. SOHOLFIELD, OF PROVIDENOE, .RHODE ISLAND/ MACHINE FOR PRINTING LINEAR MEASUREMENTS UPON FABRICS.

SPECIFICATION forming part of LettersPatentNo. 230,441, dated July 27, 1 880.

' Application filed January 15, 1880.

To all whom it may concern:

Be it known that I, J osEPH J. SOHOLFIELD,

of Providence, in the State of Rhode Island,

have invented an Improved Machine for Measuring, Registering, and Packaging Fabrics, of which the following is a specification.

My invention relates to an improved machine for graduating and registeringthe linear measurement of textile and other fabrics and for rolling the graduated and registered fabrics into suitable convenient packages for transportation or sale.

It also relates to an improved method of measuring elastic fabrics, which consists in measuring and marking upon the fabric a certain standard linear unit, and adjusting the movement of an indicating, graduating, or registering mechanism to compensate for the resulting stretch of the fabric when placed under tension in the machine, as determined by comparison with the fixed original standard unit of measurement.

The object of this invention is, first, to correctly measure in the same machine fabrics having different degrees of elasticity; second, to automatically affix graduated numerals or other marks upon the surface of the material, to indicate the number of units of linear measurement contained in the whole webor a portion thereof; third, to fold a fabric longitudinally; and fourth, to roll an elastic fabric into a convenient package under an approximately uniform tension, thus preventing injurious distortion of the graduated and registered meas urement in the resulting roll or bolt.

Fig. 44 is a sectional view of the Same, taken in a vertical plane at the front edge of the web. Fig. 45 is a partial vertical section, showing an edge view of the link for connecting the ends of two similar webs, and also showing the attached cam-piece for automatically raising the graduating and registering mechanism from the web. Fig. 46 is a plan view of the link-piece for connecting the ends of the webs. Fig. 47 is a plan view of the table and measuring-bar for imprinting the standard linear unit upon the edge of the web, as a guide to the subsequent correct adjustment of the graduating and registering mechanism.

In the'accompanying drawings, (see Figs. 41 and 42,) A represents a web of wide goods rolled upon a spool, B, which is held in an upright position by means of the step a and upper bearing, 1). The web A passes from the spool B around the upright roll B, and thence to the folder 0, which is attached to the adjustable table D,located in a horizontal plane passing through the middle of the web A, as held upon the spool B, and consists of a bedpiece, 0, made in any desirable width, a tongue, d, adjustably held in the screw-clamp e, which is pivoted to the bed 0 at the points a e, and the top piece, 1'', pivoted to the bed 0 at the points f f, and slotted at g, in order to suitably hold the adjustable guide It for operating upon the folded edge of the fabric.

The adjustable table D is pivoted to theframe E at the points d d, and is held at a suitable inclination lengthwise of the web by means of the pawls j j and thenotches ltkunder the table. The table D may also be inclined crosswise of Fig. 39 is a vei tithe web by means of adj usting-screws c 0, one above and one below the pivot d, as shown in elevation, Fig. .4.

The tension-roll F, located at a short distance in advance of, and above the plane of, the table, may be slightly frictioned by suitable means, in order to arrest the motion of the roll at the instant of stopping the movement of the measuring mechanism and to suitably augment the friction of the web upon the surface of the tension-roll F, both rolls being preferably made as light as practicable and covered with vulcanized india-rubberor other suitable frictional material.

The roll F is provided at one end with the friction-wheel f, to be operated upon adjustably by means of the weighted lever G, pivoted to the frame E at the point g, and provided upon the upper surface of its short arm with an attached friction-facin g, H, preferably made of wo n or felted fabric, which, by producing a u "orm degree of friction, tends to secure a correspondingly uniform tension in the web, which is an indispensablerequirement to correct measurement and registration.

Upon each side, at the top of the frame E, are placed the vertically-slotted standards I I and 1 1 which constitute the journal-bearings for the pressure feed-rolls J J and J J the lower rolls, J and J being connectedly driven by means of the gear K upon the shaft of theintermediate roll, J gear K and K, n pou the shafts of the rolls J' and J respectively, and the loose intermediate gears, K K, all of equal size. The upper rolls, J and J are made com 'iaratively heavy, and are turned in their bearings by frictional contact with the upper surface of the web, or with the surface of the lower rolls, J J which are prefcra-bl y covered with vulcanized india-rubbei'.

The above-described upper and lower feedrolls may, however, be geared together, so as to be strictly positive and equal in their movement, if preferred.

The upper ends of the standards I l and P 1 are connected by the loosely-fitted rods G G held in position by the inside collars, .0 .0

The rectangular frame L, provided with a projecting arm, 'L, which rests upon a cam, L secured to the loose rod G is pivoted to the rod G, and is provided upon its under side with thejournal-boxes l l, to receive the shaft m, upon which is rigidly secured the wheel M, employed. for graduating and registering the linear measurement of the fabric, being provided upon the exterior of its rim with the studs 7) 1) I), for ii'nprinting graduations of fractional parts of the unit, and upon the inner side of its rim with the transversely-arranged type-wheels m and m adjoining each other and provided upon their peripheries with engraved numeral figures, to imprint upon the surface of the fabric the units and tens, as required, to indicate the proper number of yards or other linear units of measurement in the web. The wheels m m are placed loosely upon a pin, a, passing through the standards at and a", connected to each other bymeans of the back plate, n which is securely attached to the fiat plate of the wheel M, so'as to cause the type-faces of the wheels m m to project a suitable distance beyond the outer periphery of the wheel M.

Upon the hub of the loose unit-wheel m is rigidly secured the gear 0, provided with any desirable number of teeth, and-engagin g with a similar gear, 0, attached to the shaft 1) and upon the hub of the tens-wheel m is rigidly secured the gear 0 provided with ten teeth, which are made concave upon theirouter ends to secure the pitch-line locking-surface of the single-toothed gear 0, secured to the shaft 1). Thus, upon a complete revolution of the unitwheel m the tens-wheel at will be thrown forward on e-tenth of a revolution, and there be retained by the interlocking surfaces of the gears o and 0 until the wheel m has again completed a revolution.

Upon one end of the shaftpis securely fastened the bevel-gear pinion 0 engaging with the bevel gear 0 turning loosely on the stud 12 attached to the back plate, a To the hub of the gear 0 is securely attached the scrollspring q, inclosed in a fixed case, q, and provided with an attached friction-rin g, q, whereby. when the spring has been wound up to its extreme tension, the consequent slipping of the frictionringaround the inner side of the rim of the case (1 will prevent the breaking of the spring or injury to other parts of the positively-driven mechanism. The spring q serves to automatically return the type-wheels m and m to the zero-point whenever the graduation and registration of the web has been completed.

At the opposite end of the shaftp is rigidly secured the gear 0 engaging with the gear 0 attached to the shaft 19, which is held in the forked journal-box r, pivoted at the points 1 r to the fixed standard 8, so that the gear 0 provided with ten teeth and rigidly secured to the outer end of the shaft 19', may be 'dis'engaged from the fixed cam t by the action of the spring 1*, without at'the same time disengaging the gears 0 and 0 When the gear 0 of ten teeth is placed in engagement with the fixed cam 25, and the wheel M revolved in the proper direction, the unit'wheel m will be moved progressively forward through a space equal to one-tenth of its periphery, and thus increasing one unit at each revolution of the wheel M, and for every ten units of movement imparted. to the unit-wheel m a single ten-unit movement will be imparted to the tens-wheel m and upon raisin g the gear 0 from its engagement with the cam t the action of the spring (1 will immediately return the wheels m and m to the zero-point, as indicated by the pin it upon the hub of the gear 0 and which strikes against the end of the pawl a, held in contact with the hub of the gear by means of the spring I The earn it rests loosely upon the hub of the ventthe cam from revolving with the wheel.

One-half of the periphery of the cam is cut into a screw-thread having a pitch double that corresponding to the teeth of the gear, the remaining half of the periphery being cut in a plane directly at right angles to the axis of the cam, so that during one-half of the revolution of the wheel M the gear 0 will be moved through the space of one tooth, or onetenth of a complete revolution, and will continue at rest during the remaining half of the revolution of the wheel.

At one side of the journal-box r is attached a dependent arm, 1', which engages with the beveled sleeve 2;, provided with the ears a, and sliding loosely upon the hub of the fixed cam t.

An inclined link-connection, 'w, is made from the ears 1) of the beveled sleeve to the'fixed standard 00, attached to the frame E, so that when the outer end of the frame L is raised by means of the cam L or otherwise, the link to will, cause the sleeve Q) to be drawn back, and thus allow the spring r to withdraw the gear 0 from its previous positive engagement Withthe cam t, and upon againlowering the outer end of the frame L, by turning back the cam. L the resulting downward movement of the sleeve 2; will cause it to be thrown forward by the action ofthe inclined link to, so that the beveled face of the sleeve, acting upon the dependent arm 4*, will cause the gear 0 to be again thrown into positively-held engagement with the cam 25.

Upon the outer end of the arm L is pivoted the gravitating latch 1, extending inwardly between the guiding-ears y.,and serving, in conjunction with the stop 11 fixedly attached to the plate of the wheel M, to prevent said wheel from making more than one revolution in a backward direction.

The scroll-spring'Z is attached atone end to the wheel M, and at the opposite end to the hub of the friction-wheel Z, made to fitloosely on the shaft m, and held in the adj ustable fric- (ion-clam p Z, which is prevented from moving with the friction-wheel by means of asuitable connect-ion made to the frame L, so that upon starting the wheel M in the proper direction to wind up the spring Z the frictioirwheel Z will remain stationary until the tension of the spring has become fully equal to thefrictional resistance produced by the clamp Z", and the continued movement of the wheel M will then operate to revolve the friction-wheel Z against the frictional resistance of the clamp.

The gear N is removably'attached to the outer end of the shaft m, andis held from turning upon the shaft by means of a sliding catclrsleeve, t, which is also prevented from turning on the shaft by means of a slot, l and pin i and thrown forward in the direction of 'the axis of the shaft by means of the spiral spring I, which enclrcles theshaft within the inclosing-sleeve.

IIO

The hub of the gear N is provided upon its inner face with an inclined notch, 1 to receive the catch-pin 1, attached to the face of the sleeve.

The inclined notch l and the catch-pin I, held against the face of the hub by means of the spring 1", will allow the gear N to be turned in a backward direction without imparting movement to the wheel M, thus preventing breakage in case the machine is inadvertently turned backward after the wheel M has been brought to a stop by the action of the latch y.

Whenever the frame L is placed in its lower position the gear N will engage with the gear N, which is removably attached to the shaft j of the intermediate roll, J; but upon raising the frame L so that the gears N and N become disengaged, the tension of the spring Z, operating against the friction of the clamp Z, will cause the wheel M to turn backward un til the stop y comes in contact with the end of the latch '1 thus automatically bringing the wheel M, balanced by the weight m in all cases to the proper fixed position for commencin g the registration of a web. Upon the shaftj, at the end of the intermediate roll, J, is loosely fitted the short impression-roll J made to press the web against the type-wheels, so as to make an imprint upon the selvage.

The inking a iiparatus L is adjustably and removably attached to the platform L located at the pivoted end of the frame L, by means of a screw, Z and slot 1 and consists of an inkreservoir, it, an ink-feeding roll, avibratin g ink-distributing roll, it, operated from side to side by means of the cam 70', the inkingrolls k k, driving-gears 10' W, and wheel k, by the frictional contact of which with' the periphery of the wheel M a proper rotary movement will be imparted to the inking-rolls.

The inking-rolls k It should be driven at about the same surface-speed as that of the printing-type attached to the wheel M.

To the shipper-fork O, pivoted to the journal-bearing R at the point i is jointed the sliding shipper-rod O, operated, by means of the spring to throw the belt from the tight to the loose pulley, and held in proper position for action by means of a notch in the shipper-rod. Connection is made to the spring shipper-rod 0 from the frame L by means of the hooked link L Upon lifting the shipper-- rod so that the holding-notch is released from its catch the action of the spring 0 will cause the belt to be shifted from the tight to the loose pulley, and thus stop the motion of the machine.

To the inner side of the pivoted frame L is attached the arm M, to the lower end of which is secured the loose cam 1W which serves, in conjunction with the cam-rib M attached to the web-connectin g link'piece N to automatically raise the frame L and its attached mechanism, thus causing the automatic readjustment of the type-wheels to their zero-point upon the completion of the measurement and graduation of means of the screws 8 s, as desired.

the forward web, preparatory to the continued measurement and graduation of the succeeding web.

The roll J is connected with the drivingshaft P by means of the pinion P, attached to the driving-shaft, and the gear P attached to the shaft of the roll J. The driving-pulley P fixedly attached to the shaft P, is connected by belt with the pulley Q fitting loosely upon the shaft R, held in the bearings R and R attached to the frame E. Between the two bearings R and R and adjoining the pulley Q, is placed the friction-wheel S, fixedly attached to the shaft It, and provided with a friction-clamp formed in two parts, S S, connected by the screws 8 8, provided under their heads with the springs s shwhereby an adjustable yielding pressure may be produced against the periphery of the friction-wheel. A pin, 8 attached to the side of the pulley Q, enters a hole or slot, 3 made in the projection it upon one of the parts S of the frictionclamp. The clamp S S should be lined with a woolen or felted fabric, 8 which will tend to secure comparative uniformity in the frictional results produced.

The amount of power transmitted to the shaft B may be varied and controlled by adjusting the pressure of the spring-clamp S S upon the periphery of the friction-wheel by The inner end of the shaft R isprovided with the socket-opening T to receive the socket of the square tapering mandrel r (shown in Fig. 33,) and upon which the fabric is to be wound to form a roll. Upon the inner end of the shaft R is fixedly attached the friction-Wheel R provided on its front face with the shallow grooves 0' r made eccentric to the axis of the shaft, for the purpose of holding one end of the flat mandrel T, which is employed to wind the fabric around a board, 10 to form a bolt.

The friction-wheel R is provided upon its grooved periphery with a friction-strap, R, lined with a woolen or felted fabric, 8, and attached at one end to the lug R and at the opposite end to the regulating-lever U, which is also pivoted to the lug R Upon the lever U is placed the sliding carriage U, provided upon its upper edge with an upright stud, a, for the purpose of holding a variable number of weights suited to produce the proper amount of frictional resistance upon the periphery of the wheel R Oounterbalancing-weights are also to be placed upon the upright stud u, fixedly attached to the outer end of the lever U. The flat mandrel T, for rolling the fabric into a bolt upon a board,is held in proper position to be rotated by means of the swivelshaft V, provided with a socket-opening, 'v, by means of which the shaft V may be made to rotate within the sleeve V. The shaftV is held within the sleeve V by means of the shoulder 11 and nut 19.

vided with a fixed hand-wheel, V and is operated forward and back within the bearing V The sleeve V is pro-' in order to either hold or releasethe mandrel T by means of a screw or cam-slot, v and pin '0 The flat mandrel T isrprovided at one end with a cross-piece, t having in the center of its outer edge a pyramidal socket, it, made to fit the socket opening of the shaft V. H

The spurs t t extend inwardly from the head or cross piece t and serve to hold one end of the board 12 in place while rolling the fabric thereon, the opposite end of the board being similarly held by means of the loose sliding piece T, provided with the spurs 25 t To the rocking shaft W, held loosely in bearipgs attached to the frame E, is attached the flat curved regulating-arm W, held up against the mandrel T by means of a spring placed upon the rocking shaft.

Motion is transmitted from the shaft W to the sliding weighted carriage U by means of the arm W attached to the shaft W, the link and the lever W pivoted at the point and provided with a slotted opening, w at its upper end, to receive the pin or screw by means of which it is connected to the-carriage.

v The regulating-arm W will become depressed as the fabric is being wound upon the mandrel, which will cause .the weighted carriage U to be brought gradually nearer to the fulcrum of the lever U, thus gradually diminishing the frictional resistance of the strap R upon the periphery of the wheel R Through a hole in the standard 1 just inside of the rolls J J is placed the pointer X, which is drawn back from the selvage of the web by means of the spring 00 placed between the standard I and the collar 00 At a distance from the pointer X equal to one yard or other unit of measurement, or an exact fractional division of such unit, is placed the scale X, secured at right angles to the stem or, and which is drawn back from the selvage of the web by means of the spring 00 operating between the side of the frame E and a pin or collar, ar".

The edge of the scale X may he graduated into quarter inches or other suitable uniform linear divisions, the zero-point on the scale commencing at the above-specified distance from the pointer X, with the graduations continued forward far enough to embrace within their scope the full amount of stretch properly imparted to the fabric between the pointer X and the zero-point of the scale X, in order to cause the fabric to pass smoothly between the rolls J J and J J. V

The selvage-guide Ymay be adjusted in its position to act upon the edge of the fabric by means of the screw 1 and slot y.

The pressure-plate w is held loosely upon two pins, w and is located above the table 20 which supports the edge of the web. The

. pins 10 serve, by pressing against the selvage of the web as it is held in the rolls JJ and J J to properly adjust the position of the sel-,

wheels m m sothat the imprint of the type may be made at theproper uniform distance from the edge of the web. I

The pressure-plate w is suitably held down to the upper surface ofthe web by means of the sprin g 20 attached to the supporting-standard.

Upon a platform or table, A, is hinged or pivoted the bar B provided at its ends with the studs b b set at a, distance from each other equal to the distance between the end of the pointer .X and the zero-point of the stretch-indicating scale ,X.

The studs b" b after being suitably inked upon their ends, serve to imprint a preliminary standard unit of measurement upon the edge of an elastic fabric, for thepurpose of comparison in the machine with a like unit of measurement, as indicated by the pointer X and the zero-point of the scale X, in order to determine the specific amount of stretch or elongation per standard unit of measurement resulting from the resistance of the tensionrolls upon the surface of the web.

Suitable guiding lines or marks f may be I made upon the surface of the tension-rolls F F, and also upon either of the rolls J J J J for the purpose of guiding the insertion of the forward end of the web into the machine, so that the edge of the web may, at its initial point for measurement, be properly arranged for continuous forward movement under the typewheels and in the proper line for being rolled with uniformity'upon the packaging-mandrel.

Flexible aprons N made of canvas or other suitable material and provided with a series of hooks, h h, may be employed to secure the proper tension atv each extreme of the web being attached thereto, as shown in Figs. 43 and 44, which also illustrate the improved method of ascertaining the specific stretch or elongation of the fabric arising from the applied tension, in orderv to adjust the forward movement of the graduating or registering mechanism with desirable certainty, so as to meet the requirement of the forcibly-lengthened condition of the fabric.

Several webs of the same quality may be joined end to end by means of flexible linkpieces N provided at each side with hooks h h, and having attached to their upper surfaces a cam-rib, M made of leather or other suitable flexible material, and the extreme webs of a folded pile, A may be provided with flexible leading and following aprons N N likewise attached tovthe web by means of books h It.

The forward end portion of the web at the top of the. pile, prior to its insertion into, the

machine, is to be placed upon a table, A, so that the longitudinal edge of the fabric may liein a natural unstretehed condition along the edge of the table, adjoining thehinged measuring-bar B The studs b b upon the bar, having been first inked upon their ends, are to be brought over upon the web A, as shown in Fig.47, thus imprinting upon the fabric a true vage relatively to the position of the typel standard yard or other desirable unit of linear measurement, which is to be made exactly equal to the distance from the endof the pointer X to the zero-point ot' the scale X. The end of the leading-apron N is then to be passed around the tension-rolls F F and between the rolls J J, and J J and drawn forward by the action of the rolls upon the surface of the apron and the web, until the forward mark, on, or imprint of the stud 1) upon the web has reached a point exactly opposite the end of the pointerX. Then the position of the mark a or imprint of the stud b with regard to the zeropoint 0 of the scale X will show upon inspection the exact changed or elongated condition of the web resulting from thetension applied to the same by means of the frictioned rolls F F, in order to make the web run smoothly through the machine. If the mark a falls back from the zero-point of the scale X a distance equal to one inch, then the proper and correct standard yard or other linear unit of measurement, as above imprinted upon the surface of the fabric, has been subjected to a stretch of one inch, requiring a corresponding decrease in the speed of the wheel M, to which the graduating or registering devices are attached, in order to graduate or register the fabric correctly.

A gear, N, and pinion N, with the proper relative number of teeth, having been selected and placed upon their respective shafts, the machine may be started, and the graduation and registration of the fabric he proceeded with until the terminal end of the first web has been reached, and at this point the camrib M attached to the link-piece N by passing under the cam M attached to the frame L, will cause the frame L and link L to be raised, as shown in Fig. 45, thus disengaging the spring shipper-rod 0 from its catch and causing the stoppage of the machine. The beveled sleeve '21, being at the same time drawn back by the action of the inclined link 10, allows the gear 0 to become disengaged from the cam t, and the type-wheels m m to be returned to their zero-point by the action of the spring q, and the gear N, being at the same time disengaged from its pinion N, allows the wheel M to be thrown backward by means of the spring Z to the initial starting-point for the measurement of the succeeding web. The cam-rib M attached to the link-piece N should be made of such a length, compared with the periphery of the cam M, as to allow the continued revolution of the machine to causethe type-wheels to be brought down upon the surface of the succeeding web at the proper initial point for the commencement of its graduation and registration.

If the rolls J J 2 are made just equal to twelve and one-half inches in circumference, and the wheel M calculated to graduate and register linear yards, then, for the measurement, graduation, and registration of inelastic fabrics, the gear N, with a pitch-circle of thirty-six' inches circumference, may have one hundred and forty-four teeth, and the pinion N, with a pitch-circle of twelve and one-half inches circumference, may have fifty teeth, the circumferential pitch of the teeth being one-fourth of an inch in this case. Now if we preserve the same diameters and make three additional gears having one hundred and forty-five, one hundred and forty-six, and one hundred and forty-seven teeth, respectively, to run interchangeably with the former gears, and with three additional pinions having forty-nine, forty-eight, and forty-seven teeth, respectively, for the measurement of elastic fabrics, then the proper changes in the forward movementof the wheel M can be readily effected for every quarter-inch stretch or elongation of the web from the zero-point of the scale X to the extreme of three inches.

In measuring and 'iackagingfabrics of double width the webs may be successively joined to each other by means of two link-pieces placed side by side, with the dividing-line between them at the center of the width of the web, in order that the ready folding of the fabric may not be interfered with. The joined webs, in an outspread condition, are rolled upon aspool, B, and held in an upright position, as shown in Figs. 41 and 42.

The web A is taken from the spool B around 'the upright roll B, placed in line with the revolving type-wheels, so that the edges of the web may pass from the roll B in a direct vertical plane under the type-wheels and graduating-points to the packaging-mandrel.

In order to insert the web A into the folder the top piece, f, and the: tongue (I are both turned back on their respective pivots, as shown in Fig. 26. i

The lower edge of the web, as it comes from the spool B around the roll B, is to be brought against the lowcr selvage-guide, t, the tongue (1 to be thrown into position, and the remaining upper portion of the web folded upon it and inclosed by the top piece, f, so that the upper edge of the web may rest against the upper selvage'guide, i, with the guide It held at about the thickness of the web from the end ofthe tongue (I. Theweb is passed from the folder under the tension-roll F and down under the tension-roll F, thence between the rolls 'J J and over the tapesj j running upon the rolls J J J, and between the rolls J J, to the packaging-mandrel T. The boardp upon which the fabric is to be rolled, is placed against the side of the mandrel and forced against the spurs t t. The loose clamp-piece T is then placed upon the mandrel and forced against the opposite end of the board, the penetrating-spurs t t serving to secure the board 12 firmly to the mandrel, as shown in Fig. 27

Having determined the extreme outeridimension of the bolt to be formed upon the board, the friction-clam p S S is to be adjusted so that it will transmit to. the mandrel, at the terminal portion of the bolt, sufficient power to produce the proper tension upon the fabric IIO the initial portion of the roll, owing to the increased leverage secured at the starting-point,

and in order to compensate for this increased leverage the lever U-is weighted and the limit of the movem entof' the carriage U so adj ustedthat at the starting-point of the roll or bolt,

the surplus power entering through the friction-clam S S ad'usted as above, may beabsorbed by the fixed friction-strap R so that the actual pull upon the web, when firmly held, may be made the same at both the initial and terminal portions of a roll or bolt by gradually moving the weighted carriage U" toward the fulcrum of the leverU.

The initial position of the carriage U" upon the lever U should be such that upon the completion of the roll the weighted carriage will have been brought, by the action of the armv W, arm Wt, link W and lever W, to a position near the fulcrum of the lever U, in which the counterbalancing-weights U will cause the removal of the previous tension upon the friction-strap R thus allowing the full power transmitted by the friction-clamp S S to act upon the web.

The proper adjustment of the carriage U in position upon the lever U in any case may be made by changing the angular position of the arms W and W upon the shaft W relatively to each other.

The amount of stretch or elongation arising from the friction of the tension-rolls may also be determined, before the web enters the machine, by first accurately weighing the amount of resistance encountered by a web, when the weight H, uponthe lever G, is placed in a particular notch; then, ifthepreliminary standard unit of measurement is marked upon the.

edge of the web, so as to correctly represent the true yard required to he graduated or registered, and if a weight equal to the abovementioned resistance of the tension-rolls is properly applied to the end of the web, then the comparison of the marks a a of the above measurement with the original standard yard,-

by means of which the marks were made, will indicate, as before described, the'proper change of gears to be made in any case.
